Rigrodsky & Long, P.A. announces that it is investigating potential legal claims against the board of directors of Metaldyne Performance Group Inc. ("Metaldyne" or the "Company") (NYSE: MPG) regarding possible breaches of fiduciary duties and other violations of law related to the Company's entry into an agreement to be acquired by American Axle & Manufacturing Holdings, Inc. ("AAM") (NYSE: AXL), in a transaction valued at approximately $1.6 billion.

Under the terms of the agreement, shareholders of Metaldyne will receive $13.50 in cash and 0.5 share of AAM common stock for each share of Metaldyne common stock. Based on AAM's closing stock price on November 2, 2016, Metaldyne shareholders would have received compensation valued at approximately $21.81 per share.

The investigation concerns whether Metaldyne's board of directors failed to adequately shop the Company and obtain the best possible value for Metaldyne shareholders before entering into an agreement with AAM.

If you own the common stock of Metaldyne and purchased your shares before November 3, 2016, if you have information or would like to learn more about these claims, or if you wish to discuss these matters or have any questions concerning this announcement or your rights or interests with respect to these matters, please contact Seth D.
